The index property on the event is missing

[shal1y]

The event object provides an "index" property as well which give the index of the item (if in an each block). It would be nice to have that property included in the "tap" event as well.
You can get from the keypath, but then string manipulation :(

This is causing tutorial no.10 (http://learn.ractivejs.org/partials/1/) to fail.
